According to a statement on its Facebook page on Monday, the airlines said the notice took effect on Sunday, hours after the fatal accident in which all on board the new aircraft bought in November were killed.
“Although we don’t yet know the cause of the accident, we had to decide to ground the particular fleet as extra safety precaution” Ethiopian Airlines said in the statement.
Flight ET-302 fell from the sky six minutes after takeoff from Bole International Airport in Addis Ababa on its way to the Kenyan capital Nairobi, killing all 149 passengers and eight crew members on board as it ploughed into a farmland and exploded 37 miles from the airport.
China has also ordered all of its planes of the same make to be grounded until an investigation establish that they are safe to take to the skies.
The Aviation ministry in Beijing said the same model was involved in a fatal crash in Indonesia in October shortly after takeoff.
Boeing and the US Federal Aviation Administration said they would investigate the similarities of the two incidents involving the same model aircraft.
Meanwhile Ethiopia is observing a day of national mourning on Monday for the victims of the plane crash which involved 32 nationalities.
Flags are being flown at half-mast as a sombre Prime Minister Ahmed Abiy promised a speedy investigation into the causes of the crash with a committee already set up for this purpose.
According to a tweet by his office the country’s parliament declared Monday a day of national mourning for the victims – 32 Kenyans, 18 Canadians, 9 Ethiopians, 8 Italians, 8 Chinese, 8 Americans, 7 Britons, 7 French, 6 Egyptians, 5 Dutch and a Rwandan among others.
